wings as an indicator of stress. High asymmetry indicates the bees experienced stress during development—an external factor that affected their normal growth.
Author Dr. Andres Arce, now at the University of Suffolk, stated that their"goal is to better understand responses to specific environmental factors and learn from the past to predict the future. We hope to be able to forecast where and when bumblebees will be most at risk and target effective conservation action."
Scientists from the Natural History Museum and the Earlham Institute quantified DNA preservation using just a single bee leg from each of the bees studied. From these developments, published today in, the researchers can now look to determine how the reported stress may lead to genetic diversity loss.
Author Dr. Victoria Mullin, from the Natural History Museum, say that"museum insect collections offer an unparalleled opportunity to directly study how the genomes of populations and species have been affected by environmental changes through time.
